ABSTRACT

Tuberculosis (TB) in people living with HIV (PLHIV) is usually paucibacillary and the smear microscopy has limitations and may lead to high proportions of non-confirmed pulmonary tuberculosis (NC-PTB). Despite culture being the reference method, it usually takes 6 to 8 weeks to produce the results. This study aimed to analyze the effect of a rapid molecular test (Xpert) in the confirmatory rate of PTB among PLHIV, from 2010 to 2020, in São Paulo state, Brazil. This is an ecological study with time series analysis of the trend and the NC-PTB rates before and after Xpert implementation in 21 municipalities. The use of Xpert started and gradually increased after 2014, while the rate of NC-PTB in PLHIV decreased over this time, being more significant between late 2015 and mid-2017. The city of Ribeirão Preto stands out for having the highest percentage (75.0%) of Xpert testing among PLHIV and for showing two reductions in the NC-PTB rate. The cities with low Xpert coverage had a slower and smaller decrease in the NC-PTB rate. Despite being available since 2014, a significant proportion of PLHIV suspected of PTB in the state of São Paulo did not have an Xpert ordered by the doctors. The implementation of Xpert reduced the NC-PTB rates with growing effect as the coverage increased in the municipality.

ABSTRACT

OBJECTIVE: In order to comprehensively understand the characteristics of Adaptive Business Intelligence (ABI) in Healthcare, this study is structured to provide insights into the common features and evolving patterns within this domain. Applying the Sheridan's Classification as a framework, we aim to assess the degree of autonomy exhibited by various ABI components. Together, these objectives will contribute to a deeper understanding of ABI implementation and its implications within the Healthcare context. METHODS: A comprehensive search of academic databases was conducted to identify relevant studies, selecting AIS e-library (AISel), Decision Support Systems Journal (DSSJ), Nature, The Lancet Digital Health (TLDH), PubMed, Expert Systems with Application (ESWA) and npj Digital Medicine as information sources. Studies from 2006 to 2022 were included based on predefined eligibility criteria. PRISMA statements were used to report this study. RESULTS: The outcomes showed that ABI systems present distinct levels of development, autonomy and practical deployment. The high levels of autonomy were essentially associated with predictive components. However, the possibility of completely autonomous decisions by these systems is totally excluded. Lower levels of autonomy are also observed, particularly in connection with prescriptive components, granting users responsibility in the generation of decisions. CONCLUSION: The study presented emphasizes the vital connection between desired outcomes and the inherent autonomy of these solutions, highlighting the critical need for additional research on the consequences of ABI systems and their constituent elements. Organizations should deploy these systems in a way consistent with their objectives and values, while also being mindful of potential adverse effects. Providing valuable insights for researchers, practitioners, and policymakers aiming to comprehend the diverse levels of ABI systems implementation, it contributes to well-informed decision-making in this dynamic field.

ABSTRACT

Recombinant multiepitope proteins (RMPs) are a promising alternative for application in diagnostic tests and, given their wide application in the most diverse diseases, this review article aims to survey the use of these antigens for diagnosis, as well as discuss the main points surrounding these antigens. RMPs usually consisting of linear, immunodominant, and phylogenetically conserved epitopes, has been applied in the experimental diagnosis of various human and animal diseases, such as leishmaniasis, brucellosis, cysticercosis, Chagas disease, hepatitis, leptospirosis, leprosy, filariasis, schistosomiasis, dengue, and COVID-19. The synthetic genes for these epitopes are joined to code a single RMP, either with spacers or fused, with different biochemical properties. The epitopes' high density within the RMPs contributes to a high degree of sensitivity and specificity. The RMPs can also sidestep the need for multiple peptide synthesis or multiple recombinant proteins, reducing costs and enhancing the standardization conditions for immunoassays. Methods such as bioinformatics and circular dichroism have been widely applied in the development of new RMPs, helping to guide their construction and better understand their structure. Several RMPs have been expressed, mainly using the Escherichia coli expression system, highlighting the importance of these cells in the biotechnological field. In fact, technological advances in this area, offering a wide range of different strains to be used, make these cells the most widely used expression platform. RMPs have been experimentally used to diagnose a broad range of illnesses in the laboratory, suggesting they could also be useful for accurate diagnoses commercially. On this point, the RMP method offers a tempting substitute for the production of promising antigens used to assemble commercial diagnostic kits.

ABSTRACT

Centrioles are part of centrosomes and cilia, which are microtubule organising centres (MTOC) with diverse functions. Despite their stability, centrioles can disappear during differentiation, such as in oocytes, but little is known about the regulation of their structural integrity. Our previous research revealed that the pericentriolar material (PCM) that surrounds centrioles and its recruiter, Polo kinase, are downregulated in oogenesis and sufficient for maintaining both centrosome structural integrity and MTOC activity. We now show that the expression of specific components of the centriole cartwheel and wall, including ANA1/CEP295, is essential for maintaining centrosome integrity. We find that Polo kinase requires ANA1 to promote centriole stability in cultured cells and eggs. In addition, ANA1 expression prevents the loss of centrioles observed upon PCM-downregulation. However, the centrioles maintained by overexpressing and tethering ANA1 are inactive, unlike the MTOCs observed upon tethering Polo kinase. These findings demonstrate that several centriole components are needed to maintain centrosome structure. Our study also highlights that centrioles are more dynamic than previously believed, with their structural stability relying on the continuous expression of multiple components.

ABSTRACT

BACKGROUND: schistosomiasis is a neglected tropical parasitic disease caused by trematode worms of the genus schistosoma, which affects approximately 240 million people worldwide. the diagnosis of the disease can be performed by parasitological, molecular, and/or immunological methods, however, the development of new diagnostic methods still essential to guide policy decisions, monitor disease trends and assess the effectiveness of interventions. OBJECTIVE: in this sense, the current work summarizes the findings of a systematic review regarding antigens applied in the enzyme-linked immunosorbent assay test, which were patented and published over the last ten years. METHODS: the literature search strategy used medical subject heading (mesh) terms to define as descriptors. "schistosoma mansoni" was used in arrangement with the descriptors "immunoassay", "enzyme-linked immunosorbent assay", "elisa", and "antigens", using the "and" connector. the patent search was done using keywords, including diagnosis and schistosoma or schistosomiasis or schistosome. several databases were employed for the patent search, such as intellectual property national institute; european patent office; the united states patent and trademark office; patent scope, and google patents. RESULTS: forty-one articles were retrieved, of which only five met the eligibility criteria. seventeen patents were taken from the databases, and a brief description of the most relevant inventions is given here. CONCLUSION: schistosomiasis is considered the most important helminthic disease in worldwide. therefore, it is important to of searching for and develops diagnostic methods based on serology to reduce morbidity and mortality caused by the disease.

ABSTRACT

BACKGROUND: Implementing stroke care protocols has intended to provide better care quality, favor early functional recovery, and achieving long-term results for the rehabilitation of the patient. OBJECTIVE: To analyze the effect of implementing care protocols on the outcomes of acute ischemic stroke. METHODS: Primary studies published from 2011 to 2020 and which met the following criteria were included: population should be people with acute ischemic stroke; studies should present results on the outcomes of using protocols in the therapeutic approach to acute ischemic stroke. The bibliographic search was carried out in June 2020 in 7 databases. The article selection was conducted by two independent reviewers and the results were narratively synthesized. RESULTS: A total of 11,226 publications were retrieved in the databases, of which 30 were included in the study. After implementing the protocol, 70.8% of the publications found an increase in the rate of performing reperfusion therapy, such as thrombolysis and thrombectomy; 45.5% identified an improvement in the clinical prognosis of the patient; and 25.0% of the studies identified a decrease in the length of hospital stay. Out of 19 studies that addressed the rate of symptomatic intracranial hemorrhage, 2 (10.5%) identified a decrease. A decrease in mortality was mentioned in 3 (25.0%) articles out of 12 that evaluated this outcome. CONCLUSIONS: We have identified the importance of implementing protocols in increasing the performance of reperfusion therapies, and a good functional outcome with improved prognosis after discharge. However, there is still a need to invest in reducing post-thrombolysis complications and mortality.

ABSTRACT

Despite tea beneficial health effects, there is a substantial risk of tea contamination by harmful pathogens and mycotoxins. A total of 40 tea samples (17 green (raw) tea; 13 black (fermented) tea; 10 herbal infusions or white tea) were purchased from different markets located in Lisbon district during 2020. All products were directly available to consumers either in bulk (13) and or in individual packages (27). Bacterial analysis was performed by inoculating 150 µL of samples extracts in tryptic soy agar (TSA) supplemented with 0.2 % nystatin medium for mesophilic bacteria, and in Violet Red bile agar (VRBA) medium for coliforms (Gram-negative bacteria). Fungal research was performed by spreading 150 µL of samples in malt extract agar (MEA) supplemented with 0.05 % chloramphenicol and in dichloran-glycerol agar (DG18) media. The molecular detection of the Aspergillus sections Fumigati, Nidulantes, Circumdati and Flavi was carried out by Real Time PCR (qPCR). Detection of mycotoxins was performed using high performance liquid chromatograph (HPLC) with a mass spectrometry detector. Azole resistance screening was achieved following the EUCAST guidelines. The highest counts of total bacteria (TSA) were obtained in green raw tea (81.6 %), while for coliform counts (VRBA) were found in samples from black raw tea (96.2 %). The highest fungal counts were obtained in green raw tea (87.7 % MEA; 69.6 % DG18). Aspergillus sp. was the most prevalent genus in all samples on MEA (54.3 %) and on DG18 (56.2 %). In the raw tea 23 of the samples (57.5 %) presented contamination by one to five mycotoxins in the same sample. One Aspergillus section Fumigati isolate from green tea beverage recovered form itraconazole-Sabouraud dextrose agar (SDA) medium, presented itraconazole and posaconazole E-test MICs above MIC90 values. Our findings open further discussion regarding the One-Health approach and the necessary investment in researching biological hazards and azole-resistance associated with the production and consumption of tea (in particular green tea).

ABSTRACT

BACKGROUND: The treatment of acute ischemic stroke with cerebral reperfusion therapy requires rapid care and recognition of symptoms. OBJECTIVE: To analyze the effectiveness of implementing protocols for acute ischemic stroke in reducing care time. METHODS: Systematic review, which was performed with primary studies in Portuguese, English, and Spanish published between 2011 and 2020. INCLUSION CRITERIA: study population should comprise people with acute ischemic stroke and studies should present results on the effectiveness of using urgent care protocols in reducing care time. The bibliographic search was conducted in June 2020 in the LILACS, MEDLINE, Embase, Scopus, CINAHL, Academic Search Premier, and SocINDEX databases. The articles were selected, and data were extracted by two independent reviewers; the synthesis of the results was performed narratively. The methodological quality of articles was evaluated through specific instruments proposed by the Joanna Briggs Institute. RESULTS: A total of 11,226 publications were found, of which 35 were included in the study. Only one study reported improvement in the symptoms-onset-to-door time after protocol implementation. The effectiveness of the therapeutic approach protocols for ischemic stroke was identified in improving door-to-image, image-to-needle, door-to-needle and symptoms-onset-to-needle times. The main limitation found in the articles concerned the lack of clarity in relation to the study population. CONCLUSIONS: Several advances have been identified in in-hospital care with protocol implementation; however, it is necessary to improve the recognition time of stroke symptoms among those who have the first contact with the person affected by the stroke and among the professionals involved with the prehospital care.

ABSTRACT

Mothers', fathers', or guardians' support for disclosures of diverse gender identity has significant relationships with decreased suicidality for transgender children and adolescents. They play an essential role in facing transphobia, protecting trans children, and strengthening the expression of their identity. These guardians need structural, emotional, and informative support; they need to be prepared to recognize and manage of their own feelings, as well as deal with the challenges that come with new social contexts of transphobia in schools, health institutions, and other community spaces. This study aimed to analyze the scientific evidence on the dynamics of secondary social networks to support mothers, fathers, or guardians of transgender children and adolescents. This is a systematic review of qualitative studies, guided by PRISMA guidelines. Controlled and free vocabularies were used to survey the primary studies in the following databases: EMBASE; Scopus; MEDLINE; Cumulative Index to Nursing and Allied Health Literature (CINAHL); PsycInfo; Latin American and Caribbean Literature in Health Sciences (LILACS); and Web of Science. A total of 28 articles made up the final sample of this review. Secondary social networks were described as fragile, characterized by conflicting and broken ties with healthcare services and professionals, isolation and unpreparedness from schools, and emotional and informational support from peer groups and some qualified healthcare professionals. The literature shows the potential of the dynamics of secondary social support networks; however, it presented the unpreparedness of professionals and institutional policies for welcoming transgender children and adolescents and their families, with the peer group being the main emotional and informative support network.

ABSTRACT

Mothers, fathers, or guardians of children and adolescents who do not identify with the gender they were assigned at birth face barriers in their social network to recognize their children's gender identity. This study aimed to analyze the scientific evidence on the dynamics of primary social networks to support mothers, fathers, or guardians of transgender children and adolescents. This is a systematic review of qualitative studies guided by the PRISMA guidelines. Controlled and free vocabulary were used to survey the studies in the EMBASE, Scopus, MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycInfo, Latin American and Caribbean Literature in Health Sciences (LILACS), and Web of Science databases. A total of 21 studies composed the final sample. Primary social networks were described as fragile and conflicting family/blood relationship ties with disapproval, isolation, rejection, a lack of understanding, and feelings of exclusion were expressed. Some have lost friends, reported tension in marriage and with relatives, and were commonly treated with hostility and harassment. Social transition does take place in the mutual context of struggle and resistance which demands a support network for parents or guardians.

Conclusões Vários avanços foram identificados no atendimento intra-hospitalar com implantação de protocolo; porém, é necessário melhorar o tempo de reconhecimento dos sintomas do AVC entre aqueles que têm o primeiro contato com a pessoa acometida e entre os profissionais envolvidos com o atendimento pré-hospitalar.

ABSTRACT

The actin motor protein myosin VI is a multivalent protein with diverse functions. Here, we identified and characterised a myosin VI ubiquitous interactor, the oral-facial-digital syndrome 1 (OFD1) protein, whose mutations cause malformations of the face, oral cavity, digits and polycystic kidney disease. We found that myosin VI regulates the localisation of OFD1 at the centrioles and, as a consequence, the recruitment of the distal appendage protein Cep164. Myosin VI depletion in non-tumoural cell lines causes an aberrant localisation of OFD1 along the centriolar walls, which is due to a reduction in the OFD1 mobile fraction. Finally, loss of myosin VI triggers a severe defect in ciliogenesis that could be, at least partially, ascribed to an impairment in the autophagic removal of OFD1 from satellites. Altogether, our results highlight an unprecedent layer of regulation of OFD1 and a pivotal role of myosin VI in coordinating the formation of the distal appendages and primary cilium with important implications for the genetic disorders known as ciliopathies.

Abstract Objective To analyze correctional officers' role in HIV/AIDS care in the prison system. Methods This is a narrative literature review, whose bibliographical search was carried out using controlled and free vocabularies, derived from the words "correctional officer" and HIV/AIDS. The survey was carried out in the LILACS, MEDLINE, Embase, CINAHL and Scopus, Academic Search Premier and SocINDEX databases using the Boolean operators AND and OR. Studies published in Portuguese, English and Spanish that answered the study's guiding question were included. Duplicate articles, those that did not answer the study question and secondary studies were excluded. Results A total of 3,036 publications were retrieved that went through three selection stages, which resulted in nine studies included in the review. Four main roles played by correctional officers in HIV/AIDS care in the prison system were identified: regulation of access to medical services; collaboration and performance of HIV transmission prevention activities in prisons such as condom distribution; carrying out health education actions; monitoring inmates in consultations, examinations and admissions outside the prison; and drug replacement planning. Conclusion Correctional officers are expected to assist healthcare professionals in HIV/AIDS prevention and treatment, referral and monitoring of inmates to care within and outside the prison system, distribution of condoms, carrying out health education actions and help in forecasting of medicines.

ABSTRACT

OBJECTIVE: To identify and synthesize the scientific knowledge produced regarding the effectiveness of the GeneXpert test in the diagnosis of pulmonary tuberculosis (TB) in people living with HIV/AIDS. METHODS: Integrative literature review, which was searched on Embase, Scopus, PubMed, Cinahl, Academic Search Premier, Socindex, and LILACS platforms, in December 2019. The studies surveyed went through two stages of selection: reading of titles and abstracts by two reviewers independently; using the Rayyan platform and reading. Nineteen primary studies in English, Portuguese, and Spanish that answered the study's guiding question were included: How effective is the GeneXpert test in the diagnosis of pulmonary TB in people living with HIV/AIDS? RESULTS: The use of GeneXpert substantially increased the detection of TB cases among the population co-infected with HIV/AIDS, with sensitivity ranging from 68% to 100%, superior to sputum smear microscopy. Specificity ranged from 91.7% to 100%; the positive predictive value from 79.2% to 96.1%; and the negative predictive value from 84.6% to 99.3%. These values were considered similar to sputum smear microscopy by most studies. We also compared these results with different ways of performing culture and other molecular tests, being considered inferior only to the Xpert Ultra. CONCLUSION: It is possible to affirm that places with a high incidence of HIV/AIDS would benefit from the implementation of the GeneXpert test, entailing effectiveness in diagnosing pulmonary TB in this population when compared to sputum smear microscopy, a widely used test for detection of cases.

ABSTRACT

Adulto jovem de 18 anos que evoluiu após traumatismo craniencefálico leve com fístula carotídea direta. Apresentou zumbido e exoftalmia, ambos de característica pulsátil e à esquerda. Foi submetido a estudo com Doppler das carótidas, que mostrou elevadas velocidades do fluxo sanguíneo e índices de resistência reduzidos nas artérias carótidas comum e interna esquerdas, compatíveis com fístula carotídea direta. A angiotomografia computadorizada cerebral confirmou a fístula carotídea. Foi encaminhado para tratamento endovascular por embolização, com sucesso. O Doppler de carótidas pode ter papel importante no diagnóstico das fístulas carotídeas diretas e acompanhamento de pacientes submetidos à terapêutica endovascular.(AU)

RESUMO OBJETIVO Identificar e sintetizar o conhecimento científico produzido a respeito da efetividade do teste GeneXpert no diagnóstico da tuberculose (TB) pulmonar em pessoas vivendo com HIV/aids. MÉTODOS Revisão integrativa da literatura, cuja busca foi feita nas plataformas Embase, Scopus, PubMed, Cinahl, Academic Search Premier, Socindex e Lilacs, em dezembro de 2019. Os estudos levantados passaram por duas etapas de seleção: leitura dos títulos e resumos por dois revisores de forma independente, utilizando a plataforma Rayyan e leitura integral dos mesmos. Foram incluídos 19 estudos primários em inglês, português e espanhol que respondiam à pergunta norteadora do estudo: Qual é a efetividade do teste GeneXpert no diagnóstico da TB pulmonar em pessoas que vivem com HIV/aids? RESULTADOS A utilização do GeneXpert aumentou substancialmente a detecção de casos de TB entre a população coinfectada com HIV, com sensibilidade que variou de 68% a 100%, sendo superior à baciloscopia. A especificidade variou de 91,7% a 100%; o valor preditivo positivo, de 79,2% a 96,1%; e o valor preditivo negativo, de 84,6% a 99,3%, valores considerados semelhantes à baciloscopia pela maioria dos estudos. O teste também foi comparado com as diferentes formas de realização da cultura e outros testes moleculares, sendo considerado inferior apenas ao Xpert Ultra. CONCLUSÃO É possível afirmar que locais com alta incidência de HIV se beneficiariam com a implantação do teste GeneXpert, uma vez que sua efetividade no diagnóstico da TB pulmonar nessa população é expressiva quando comparada à baciloscopia, teste que foi por muito tempo amplamente utilizado para a detecção dos casos.

ABSTRACT

OBJECTIVES: to analyze the care provided to individuals with Tuberculosis (TB)-HIV coinfection in prison units in the state of São Paulo, according to the regional coordination of prisons. METHODS: cross-sectional study conducted between 2016 and 2018. A structured questionnaire was applied to 112 directors or health professionals from 168 prison units. Data were analyzed by frequency distribution and multiple correspondence analysis. RESULTS: 92.9% of participants reported active search for respiratory symptoms, 89.3% offer the directly observed treatment (DOT) for all TB cases, 95.5% anti-HIV testing for all inmates, 92.9% offer HIV follow-up in specialized care services and 59.8% antiretroviral drugs for cases of coinfection. An association was identified between the Northwest and Central regional coordinations and deficient human resources and low performance of actions for the diagnosis and follow-up of cases. CONCLUSIONS: although most prison units perform planned actions for the care of coinfected persons, some places need support to guarantee access to these actions.

ABSTRACT

BACKGROUND: The present study performed a systematic review and meta-analysis of clinical trials using bisphosphonates for bone demineralization in human immunodeficiency virus (HIV) patients. METHODS: A comprehensive literature search was performed from January 2004 to January 2020 considering the bone mineral density (BMD) of the lumbar spine (LS) as the main outcome. Out of 214 titles that met criteria, 9 studies fulfilled the selection criteria. RESULTS: A total of 394 patients were identified, and they were allocated into 2 groups: the intervention group (200 patients), to whom a combination of alendronate or zoledronate with calcium and vitamin D was administered; and control group (194 patients), to whom only calcium and vitamin D was administered. Clinical profile and indicators of bone metabolism of the participants were evaluated regarding effect size, homogeneity, and consistency. No substantial heterogeneity between the groups was found for the baseline variables, and there was high consistency to the main outcome. The meta-analysis shows a significant difference in post-treatment BMD, favoring the intervention over the control treatment. The intervention improved LS density up to 0.227 g/cm², raising the average to the levels of general population. Adverse effects related to intervention were fever immediately after zoledronate administration and gastrointestinal complaints during alendronate usage. Other adverse effects were barely reported and poorly connected to intervention by studies' authors, despite all of them have been successfully resolved. CONCLUSIONS: This study provides evidence that BMD post-treatment is better in HIV patients who used bisphosphonates combined with calcium and vitamin D.
